Spring Festival approaching spring security vehicle anti-theft technology

As the Chinese New Year approaching, many friends who are visiting relatives and friends are worried about their own car security issues. This article will provide vehicle security tips for everyone!

The trick of stealing cars is big. 1. Steering wheel lock cannot be locked. Many owners like to lock the steering wheel with a steering wheel lock, but such locks are virtually useless for "experienced" car theft thief, steering wheel lock is very strong, but only need a saw blade, saw the gap in the steering wheel, you This "security system" was destroyed.

2. Master key to the marble lock. Billet locks are very popular. The so-called pin locks use a plurality of pop-up locks to jam the sticks so that they cannot be linked to the trigger switch mechanism behind them. But the master key almost got everything, and the hard homemade steel piece was forcibly inserted into the lock hole, which called the lock gallbladder to rotate, and opened the lock.

3. Anti-theft alarm is not anti-theft. Some people are stunned with alarms equipped with sensitive vehicles that pass through the side of the car and raindrops on the body. They do not know that this is a thief seizing the handle. First of all, they will pat the vehicle, causing a very short alarm, followed by smashing the window... The alarm will vibrate again, pick up the alarm and stop the alarm. The characteristics of the anti-theft device being sensitive to raindrops and thunder were fully utilized. Some thief-robbies were therefore particularly prone to rain.

4. Copy owner identity. The general top luxury car is not just a name, of course, is also reflected in its anti-theft system, otherwise easily millions of cars easily stolen away, I am afraid that insurance companies have also put such vehicles on the blacklist. But there is still a big Ben, BMW was stolen away, the high-level technology set down a lot of mystery, under the cover of the road level so vulnerable to attack? The answer is also that if anyone obtains the owner’s detailed personal data through the dealership and has prepared a legal key, it will be hard for anyone.

Car anti-theft technology assembly car theft has a variety of anti-theft products and original anti-theft devices. Automobile anti-theft products are divided into two major categories, mechanical anti-theft products and electronic anti-theft products. Mechanical anti-theft products have wheel locks, locks and steering wheel locks. Electronic anti-theft products from the general electronic anti-theft device to mobile phone remote control GSM and satellite positioning GSP. Here we introduce one by one the characteristics, advantages and disadvantages of each type of anti-theft products.

Mechanical anti-theft products wheel lock: As the name suggests, the wheels are locked on the wheels so that the wheels can not be turned to achieve the purpose of theft.

Advantages: The wheel locks are generally very heavy and heavy, and it is almost impossible for a car thief to damage the wheel lock body. It is less likely that the wheels that lock the wheel lock will be replaced by one wheel to drive away the car.

Disadvantages: The wheel lock's anti-theft performance depends on the lock cylinder it uses. If its lock cylinder is a garden-shaped keyhole, a glyph, a cross or other ordinary lock hole, the wheel lock is not safe. Because these common lock cylinders can be strongly twisted within seconds using special tools.

In addition, the wheel lock is used outdoors, wind and rain, coupled with the lock cylinder and the ground is very close, the lock cylinder is very easy to damage. For example, if the car is parked on mud, after a heavy rain, sediment enters the lock cylinder, and the wheel lock may not open again.

Gear locks: There are two types of gear locks, one of which requires riveting of a piece of steel plate on the body and a lock body of a generic padlock to be fixed on the steel plate.

Advantages: The shift lever can be locked in the parking position to prevent the car from moving away. The use of gear locks is more convenient.

Disadvantages: Not enough security. For most cars, the car thief simply opens the front cover of the car and pulls the gear from the front of the car to hang the car.

Steering wheel lock: It is the most used anti-theft tool for car owners.

Advantages: It's cheap, it's not too much trouble to use, and it gives the owner a feeling of practicality after use. In addition, if an emergency occurs, it can also be a self-defense weapon.

Disadvantages: The outer circle of the steering wheel and the spoke are made of plastic-encapsulated very small aluminum alloy tubes (about one centimeter in diameter and about one millimeter in wall thickness). With a one-foot long iron shear, the steering wheel outer ring or spoke can be easily cut in seconds. Then remove the steering wheel lock from the incision and throw it away. The entire process takes only 6 to 60 seconds! If your steering wheel lock uses a round key hole or other common key hole, it is even simpler. The car thief uses a special tool to twist the lock cylinder and unlock it. It may be faster than you unlock it with your keys.

Mechanical anti-theft products are one of the simplest and cheapest on the market. Their principle is to lock the steering wheel and control pedal or stop. Its advantages are that it is cheap and easy to install; its disadvantage is that the anti-theft is not thorough, and the mechanical anti-theft device is mainly used to restrict the operation of the vehicle, and the help provided by the anti-theft device is limited, and it is difficult to resist the shovel, hacksaw and scissors. Theft of heavy tools. However, if criminals use special locking tools or highly corrosive chemical reagents to erode the lock cylinder through the lock hole, stealing the car is only a matter of minutes. In addition, each time the disassembly is troublesome, it is also necessary to find a place to place it when not in use

Electronic anti-theft products electronic anti-theft device: electronic anti-theft device is installed in the car electronic anti-theft device, so as to achieve the purpose of monitoring the vehicle and alarm. This is the most popular and most expensive anti-theft device, and its popularity may not be comparable to other anti-theft devices.

Advantages: Regardless of whether the engine cover, luggage compartment and doors are opened, the vehicle is collided or lifted off the ground, or someone breaks into the car, etc., the alarm sounds to alert the owner and others.

Disadvantages: After the popularity of this anti-theft device, some car thieves have developed measures. Whether it is a simple code hopping or a fixed code, it can be coded in a few seconds by a dedicated decoder. Moreover, this type of anti-theft device often causes false alarms and generates noise that disturbs people. People are also accustomed to this, and their anti-theft effect is greatly reduced. To deal with car grabbing and vehicle towing, this kind of anti-theft device is powerless. If the car owner is far away from the car, it is difficult to recover after being stolen.

Car anti-theft: armed to the leg GPS satellite positioning system GPS satellite positioning system is the most advanced anti-theft device at home and abroad.

Advantages: The current GPS system has a variety of functions such as vehicle location, network security, remote shutdown, car listening, anchor rescue, traffic information, manual navigation, and vehicle inquiries.

Disadvantages: At present, it is not very popular. The main reason is that the price is too high. Light installation of a GPS without a display would cost 6000-7000 yuan, and each year it would need to pay a service fee of nearly one thousand yuan to a GPS system service company. The high purchase and use fees made many owners discouraged. It is also subject to many blind spots, high prices, high user fees and the ability of the police to police. In addition to being easily destroyed, it also infringes the privacy of the owner.

Compared with mechanical anti-theft devices, the biggest advantage of electronic anti-theft devices is that they have alarm functions. However, the phenomenon of false alarms in electronic anti-theft devices is also common. In addition, the installation of electronic anti-theft device will inevitably change the original car circuit, if the installation is not correct, there may be conflict with the original car anti-theft system, may also cause damage to the air conditioning, interior electrical and other lines electronic anti-theft products may in principle be possible It is very advanced and complex, but they have a common weakness: If there is only one theft within the country to crack these electronic anti-theft products, he can use the crack method as a decoder or software to sell to thieves across the country through the Internet. The car thief in various places does not need much cultural and electronic knowledge, but can easily use the purchased decoder to crack the car electronic anti-theft system and drive away the car (special car decoder only 500 yuan, for any type of decoder will need 9 thousand yuan). And, to deal with the electronic anti-theft system installed after the purchase of a car, many times, the car thief does not need a decoder and specialized technology to crack. He only needs to take a moment to observe how the mechanics pull the wires of the electronic anti-theft system from the front of the vehicle to other parts. He can easily use hooks made of wire to cut off these wires and disable the electronic anti-theft system. In addition, to deal with mobile phone remote control GSM and satellite positioning GSP, simply use a mobile phone can be disabled. Therefore, electronic anti-theft products can only deter small thief, and may not have any effect on professional car thieves.

Summary of the six elite anti-theft technology In addition to the above-mentioned various common car theft prevention methods, there are many uncommon, multi-elderly methods that are equipped with high-end cars.

1, the engine to prevent the starter "anti-theft" of the highest realm is that even if the thieves enter the car, damage the line, it can not be successfully launched the car away. Currently equipped with Cadillac STS, Ford Mondeo, Opel and other models.

2. The password type anti-theft device needs to input the password before each launch. After the confirmation, the anti-theft device can be released. The owner can change the password at any time. Citroen SUVs and other leisure and long-distance tourers are equipped.

3. The infrared detector uses an infrared detector to detect any disturbances in the vehicle. As soon as there is movement, the anti-theft system will start immediately. Porsche 911 and other equipment.

4. The air flow detection device detects slight changes in the “air density in the vehicle” through the ultrasonic sensor, thereby activating the anti-theft device. Volvo and Dongfeng Peugeot 307 are equipped with such devices.

5, automatically change the password system Currently only Mercedes-Benz and BMW are equipped with such devices. The device consists of an ignition switch, an electronic preventer and an engine supervision system. The system first recognizes the key in the key and grants the “right to launch”. At the same time, the recognizer will send out a new set of passwords again. As the password for the next ignition.

6, European version of the anti-theft system digital authentication anti-theft system is a globally recognized effective start suppression system, it is difficult to crack, this type of system manufacturers very strict control, repair time-consuming and costly.

In addition, according to the condition of the vehicle, the owner can set up one or two small faults or organs that are difficult for the outsider to release. The owner can use his brains to lock the door, start the start line, and the oil circuit. The utility model can break the low voltage line in the ignition system. (The low-voltage line is concealed from the high-voltage line); or improve exterior car accessories, such as fuel tanks, batteries, lamps, etc., should be improved in the connection fastening screws, can be used instead of standard nuts, such as the pentagonal nut must use a special wrench Can be unscrewed. So if the car thief used 2-3 minutes to solve the first anti-theft lock, and the low-voltage line does not work or other measures will work, so that the thief has no time to study, had to stop looking for another goal.
